Be it known thatI, Rosoon H. Bowers, a citizen ofx the United States, residing at East Canton, in ythe county of Starkfand' State' Vof Ohio, have invented a new and useful Clamping Screw, ofwhich the followinfr is a specification.

'his invention relates to improvements in screw operating devices such as may be used in numerous forms such as glass holders for automobile doors, or any other device where a clamping action isrequired, means being provided for preventing rotation of the screw while it is moved longitudinally by means of a rotatable nut.

The above and other objects may be attained by providing a pair of parallel bearing members having aligned apertures therein, V-shaped projections extending into said apertures, the screw being provided with V-shaped grooves which receive said projections, a nut being mounted upon the screw between the bearing members.

With these objects in view, the invention consists in the construction and arrangement of parts, hereinafter described and illustrated in the accompanying drawings, it being understood that various changes in the form and details of construction may bc made within the scope of the appended claims.

In the accompanying drawing, the invention is illustrated as embodied in an automobile door glass holder, in which- Figure 1 is an elevation of the device applied to the glass of an automobile door;

Fig. 2, an elevation of the several parts of the device separated; n

Fig. 3, a longitudinal section through the device; y

Fig. 4, a perspective view of the bracket; Fig. 5, a detached perspective of the screw; Y

'Fig'. 6, a detached perspective of the nut;

' and F ig. 7, a transverse section of the device.

Similar numerals of reference indicate corresponding parts throughout the several figures of the drawing.

A portion of the irame of an automobile body is shown at 1 and a portion of the door glass at 2. The bracket 3 of the device is provided with the oppositely disposed at,`

Jcaching lugs 4 having counter-sunk apertures 5 forthe receptionof. screws vor the like,'as shown-atc.' 1

`A pair ofspaced ears' 7 are formed upon the bracket members, each ear having an aperture Sprovided with the inwardly disposed V-shaped projections 9 upon diainetrically opposite sides thereof, the apertures inY the'two ears; to slidably receive being aligned in order the screw 1() which is provided upon diametrically opposite sides with the V-shaped groove 1'1 into which the projections 9 eX- tend.

A tubular casing 12 is mounted upon one of the ears 7 in position to receive the screw, the end thereof being closed to protect the lubricate thel screw. 4

and carries the rubber button 16 arranged to engage the` surface of the door glass to hold the same from rattling.

By rotating the nut in either direction, the

screw will be moved 'longitudinally through the apertures 8 of the ears, theprojections k9 in said apertures engaging the grooves 11 in the screw, preventing the saine from rotatv70 screw. If desired, ygrease may be` placedfin is preferably cylindriing, but allowing the screw to be easily operated.

l/Vhile the screw has been illustrated as applied to an automobile door glass holder, it will be evident, of course, that the same device may be used for numerous other purposes, without departing from the invention.

Although the drawings and above speciiication disclose the best lmode -in which I have contemplated embodying my invention,

desirenotto be limited to the details of y such disclosure, for, in the furtherpractical application of my invention, many changes in forni and construction may be made, as

circumstances require or experience sug-' geste, without departing from the spirit of the invention, within the'scope of the appended claims` I claim v v1. A device ofthe character described comprising yspaced bearing members having mally house the screw, a nut upon the Screw betweenftheears and abut/tonruponltherouter end v,of thescrevv.

3. A device of the character described comprising a bracket, .spaced ears ithereon provided with aligned openings, a pair of V-s'haped'projections in each opening, a fscreiv slidably mounted through the openf ings and provided With longitudinal V- shaped :grooves receiving the projections, a tubular casing fixed upon one ear and arranged to normally house the screw 13nd :a nut `uponlthe screw J'between :the ears.

ln testimony that 11 .Eclaim fthe above, l 30 have hereunto subscribed'byname.
